Plant
Plants are the eukaryotes that form the Kingdom (biology), kingdom Plantae; they are predominantly Photosynthesis, photosynthetic. This means that they obtain their energy from sunlight, using chloroplasts derived from endosymbiosis with cyanobacteria to produce sugars from carbon dioxide and water, using the green pigment chlorophyll. Exceptions are parasitic plants that have lost the genes for chlorophyll and photosynthesis, and obtain their energy from other plants or fungi. Most plants are multicellular organism, multicellular, except for some green algae. Historically, as in Aristotle's biology, the plant kingdom encompassed all living things that were not animals, and included algae and fungi. Definitions have narrowed since then; current definitions exclude fungi and some of the algae. By the definition used in this article, plants form the clade Viridiplantae (green plants), which consists of the green algae and the embryophytes or land plants (hornworts, liverworts ...

Rubiaceae
Rubiaceae () is a family (biology), family of flowering plants, commonly known as the coffee, madder, or bedstraw family. It consists of terrestrial trees, shrubs, lianas, or herbs that are recognizable by simple, opposite leaves with Petiole (botany), interpetiolar stipules and sympetalous actinomorphic flowers. The family contains about 14,100 species in about 580 genera, which makes it the fourth-largest angiosperm family. Rubiaceae has a cosmopolitan distribution; however, the largest species diversity is concentrated in the tropics and subtropics. Economically important genera include ''Coffea'', the source of coffee; ''Cinchona'', the source of the antimalarial alkaloid quinine; ornamental cultivars (''e.g.'', ''Gardenia'', ''Ixora'', ''Pentas''); and historically some dye plants (''e.g.'', ''Rubia''). Description The Rubiaceae are morphologically easily recognizable as a coherent group by a combination of characters: opposite or whorled leaves that are simple and entire, ...

Endemism
Endemism is the state of a species being found only in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a larger area or b ...

Tahiti
Tahiti (; Tahitian language, Tahitian , ; ) is the largest island of the Windward Islands (Society Islands), Windward group of the Society Islands in French Polynesia, an overseas collectivity of France. It is located in the central part of the Pacific Ocean and the nearest major landmass is the North Island of New Zealand. The island was formed from Volcano, volcanic activity in two overlapping parts, ''Tahiti Nui'' (bigger, northwestern part) and ''Tahiti Iti'' (smaller, southeastern part); it is high and mountainous with surrounding coral reefs. Its population was 189,517 in 2017, making it by far the most populous island in French Polynesia and accounting for 68.7% of its total population; the 2022 Census recorded a population of 191,779. Tahiti is the economic, cultural, and political centre of French Polynesia. The capital of French Polynesia, Papeete, Papeete, is located on the northwest coast of Tahiti. The only international airport in the region, FaaŹ»a International ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Society Islands
The Society Islands ( , officially ; ) are an archipelago in the South Pacific Ocean that includes the major islands of Tahiti, Mo'orea, Moorea, Raiatea, Bora Bora and Huahine. Politically, they are part of French Polynesia, an overseas country of France, overseas country of the France, French Republic. Geographically, they form part of Polynesia. Name The term ''Society Islands'' was first used by Captain James Cook when he visited the Leeward Islands (Society Islands), Leeward Islands, a subgroup of six of the modern-day Society Islands, during his First voyage of James Cook, expedition to the south Pacific Ocean in 1769. It has been asserted that the name honors the Royal Society, the sponsor of his voyage, but this is disputed. Cook wrote in his journal: History Settlement The first Polynesians are understood to have arrived on these islands around 1000AD. Oral history origin The islanders explain their origins in terms of an oral tradition, orally transmitted sto ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Psychotria
''Psychotria'' is a large genus of flowering plants in the coffee family Rubiaceae, with over 1,600 species. The genus has a pantropical distribution and members of the genus are small understorey trees in tropical forests. Some species are endangered or facing extinction due to deforestation, especially species of central Africa and the Pacific. Many species, including ''Psychotria viridis'', produce the Psychedelic drug, psychedelic chemical dimethyltryptamine (DMT). Selected species * ''Psychotria abdita'' * ''Psychotria acutiflora'' * ''Psychotria adamsonii'' * ''Psychotria alsophila'' * ''Psychotria angustata'' * ''Psychotria atricaulis'' * ''Psychotria beddomei'' * ''Psychotria bimbiensis'' * ''Psychotria bryonicola'' * ''Psychotria camerunensis'' * ''Psychotria capensis'' * ''Psychotria carronis'' * ''Psychotria carthagenensis'' * ''Psychotria cathetoneura'' * ''Psychotria cernua' * ''Psychotria chalconeura'' * ''Psychotria chimboracensis'' * ''Psychotria clarendonensi ...
